Hi,
I have am trying to create functions to convert strings to ascii and vice
versa:
function string_to_ascii( $str ) {
for( $i=0; $i < strlen( $str ); $i++ ) {
$asc .= ord( substr( $str, $i ) );
}
return $asc;
}
This function works fine, however I need to ensure that the ASCII
convertions are three digits long so that I know where to split the ASCII
string when converting back to a normal string. i.e. 97 must be 097.
Thanks for any advice offered
